IMPROVEMENT EN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 4&069. dated June 6, 1865.

To all whom fit may concern:

Be it known that I, J osera INGnLs, of Mit ton, in the county of l/Vayne and Stateof Indi ana,havemadenewandusefulImprovementsin GrainDrills5 and I do hereby declare the following to be a full, clear, and exact description of thenature, construction, and operation of the same, reference being had to the accompanying drawings, which are made part of this specification, and which exhibit two substantially analogous embodiments of the novel fea tures of my invention, differing in unimportant particulars. y

Figure l is a. vertical section, and Fig. 2 a plan, of one of these forms. Fig. 3 is a view principally in elevation, and Fig. 4 is a plan of the other form.

Similar letters inthe different figures indi cate corresponding parts. l

My invention essentially consists of a method of adjusting in position and of returning to the said position the hoe after it has been deected to the rear by an obstacle.

To enable one skilled in the branch of manufacture towhich myinvention is allied to make and use the same, I will proceed to describe it.

l will speak first of the form shown in Figs. 3 and 4.

A is a drag-bar, attached at its forward end bya hanger to the frame of the drill-carriage.

Bisahoe,asitiscalledinthetrade, although it is otherwise called a flute This receives at its upper orifice the seed as it falls from the hopper, and allows it to fall into the furrow The hoe B is pivoted to the drag-bar by means of a lug, D, and pin E, and from the upper forward end of the said hoe protrudes a lug, F, which, curving downwardly, impinges upon` the spring bracebar Gr, which is secured by bolt and nut H H to the drag-bar A, The shape of this spring will be readily seen in the drawings, and it consists of a flattened portion, which is attached to the drag-bar, from thence, passing forward and downward, it forms a loop, and, recurving backwardly, has at the point 71, acurved depression, in which the point of the lug rests during the ordinary working position of the hoe.

It will also be seen thatthe bolt passes through a slot in the drag-bar, Figs. 1,2, or between the pieces, which, united, form a drag-bar, Figs. 3, 4, and is capable of adjustment forward or backward, the effect of which is to govern and control the normal position of the hoe, for when the boltH is set forward it has the effect oi' drawing forward and upward the point of the lugF and increasing the rake or inclination of the hoe. The contrary effect, I may say, though it is perhaps superiiuous, is produced by setting the bolt back in the slot I. l need hardly state that several of these hoes, similarly adjusted and controlled,are used in a gang; but it will add to the perspicuity of this paper to continue to,

speak of one of them, premising that what is said of one applies to each under similarly-impelling circumstances. When a hoe comes in contact with an immovable obstacle the former is deliected to the rear to an extent proportionate to the height of said obstacle, and the pointot' the lu g F traverses back on the springbar. It' the backward course of the point f does not extend beyond the inclined portion z' of the spring, the effect of the latter, as soon as the obstruction is passed, is to restore the hoe to its normal position with the pointfresting in the depression h.

At the end of the incline t' is a small curve, which acts as a temporary detainer to the hoe in its rearward motion, and prevents it from passing over unless the obstruction is of such a height as to compel it to do so. In this latter case the extreme point of the spring-bar G traverses the curved depression a in front of the lug F and above its pointf.

It has been my aim so to proportion the parts that obstructions which do not protrude above the surface will not deflect the hoe so far backwardl y as to be beyond the power ofthe springbar Gr to restore it 5 but when that occurs the hoe is restored to its normal position by backing the drill when the contact of the hoe with the ground, throwing the hoe forward again, places it withinwthe control of the spring, which, in connection with the resumption of the forward motion of the machine, restores the parts to their working position. l

In Figs. l, 2, 3, and 4, respectively, may be seen substantially similar modes Yof attaining the result. The difference, when any exists, is to be found in the drag-bar and the form of the lug F, whose change is incident to the change in the drag-bar.`

It will not be proper to dilate upon a comparatively immaterial modification, but it will be apparent in Figs. 1 and 2 the drag-bar is made in one piece, andis provided with a slot for the adjustment of the bolt H, while in Figs. 3 and 4 the drag-bar is made of two pieces riveted together, and affording by aspace between the bars of whlch it is composed a place for the adjusting-bolt H. Further,in Figs. 3 and 4 the lug F, as the hoe,.is made in a single horn or prong, with a rib on its edge which forms a guide as it moves within the opening between the sides of the drag-bar, while in Figs. l and 2, the horn or prong is duplicate, and the respective portions pass on each side of the dragbar. Their lfunctions are exactly similar, and it is merely a question of manipulation and economy of construction, the balance bein g in favor ofthe mode shown in Figs. 3 and f1, as it saves blacksmithing.

After tedious and protracted experiments with different-shaped springs I have determined that the one shown and described acts the incline 'a' presses forward and reinstates the hoe in its normal position. Vere this effected by aspring which proceeded im mediately backward from its point of attachment it would be liable to rupture at the said point, whereas by its recurved form it so far divides the elastic deflection as to bring no appreciable definite strain upon any one point.

Having thus described my invention, what claim therein as new, and desire to secure by Letters Patent, is-

1. The spring brace-bar G, attached to the drag-bar, and impinging at the curve h upon the end ot'. the langeFin the working position of the hoe, and having an incline upon which the point of the angerises when the hoe is deected backward, as described and represented.

2. The indentation n 0n the flange F, in which the end ot' the spring rests7 detaining the hoe from further backward deection.
